Specification of Letters latent.

Application filed February 14, 1913. Serial No. 748,289.

To all whom it may concern:

Be it known that I, SAMUEL B. Crrrrme, a citizen of the-United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Looms,of which the following is as ecification.

My invention relates to ooms and particularly to the provision of meansto facilitate the operation of taking a lease in looms equipped with astop motion.

The invention will be understood by reference to the accompanyingdrawings in which- Figure 1 is a diagrammatic view of a portion of aloom showing the use of my invention therein; Fig. 2, an enlarged endview of a portion of Fig. 1 showing my invention applied to the backwarps, a part of the construction being broken away; Fig. 3, a side viewof Fig. 2 with the drops omitted; Fig. 4 a view similar to Fig. 3 withthe compound terminal in its raised position; Fig. 5 a view showing theapplication of my inven- Fig. 6, a front view of Fig. 5; and Fig. 7 adetail of the means for coupling the terminal clamping supports.

Similar reference numerals indicate similar parts in the several views.

Referring to the drawings the numeral 1 designates the lay, 2 theharness, 3 the back warps. and 4 the pile warps of a double pile fabricloom. Such loom will be equipped with a stop motion of any of the usualforms. such motion including drop devices 5 on the back warp and similaror equivalent drops on the pile warps. In my application, Serial No.733.571, filed November 26, 1912, I have described a stop motion for thepile warps in which the drops are supported upon an inclined section ofthe warps. In Figs. 1, 5 and 6 of the present case I have shownsubstantially the same arrangement wherein the drops are carried on asection of the pile warps passing between the warp supporting rods 6,these rods being held in end pieces 7. The compound terminal which isembraced by the drops, consisting of a circuit terminal bar 8 and aterminal blade 9 set into but insulated from the bar 8, is slidablysupported in slots 10 in the end pieces 7. Rings 11, or other retainingmeans, are passed through openings 12 in the bar 8 and engage pins 13fixed in the end pieces 7. Darin the normal running of the loom, thetermmal is in the position indicated by full lines in Figs. 5 and 6. Insuch position there is not sufficient room between the warp supportingrods 6 and the terminal to permit the taking of a lease at the end ofthe warp, and it is for this purpose that I provide the slots 10whereby, when a lease is to be taken, the terminal may be raised to thetop of the slots, the rings 11 being disengaged from pins 13 and hungupon pins 13'. as shown by dotted lines in Figs. 5 and 6. \Vhen theterminal is thus raised the operator takes out the casing rods 31, thenraises one set of pile harnesses and lowers the other set, and thisleaves the threads crossed in the space between the harness and theterminal. Lease rods are then inserted, one on each side of the crossingand moved near to the terminal supporting frame. The rods spread thewarp through the frame and when so spread a rod is placed between thewarps at the left of the frame and the one nearer the frame at the rightremoved. The remaining rod at the right is then moved toward the frame,thus spreading the second part of the lease through the frame, andanother rod inserted at the left of the frame and the red at the rightthereof removed. The operator then passes the lower back warps in thesame way when the lease rods 14 will be in the position shown in Fig. 1.The new pile warp beam 15 is then conveniently placed at the back of theloom, with the lease rods 16 inserted. as shown in Fig. 1, and, theoperator breaks a thread from the end of the warp in the loom and onefrom the new warp and twists them together between the lease rods 14 and16. hen all of the ends are thus twisted. if it is desired to runwithout a lease, the operator takes out both sets of rods 1 1 and 16.The warp beam is then placed in proper position on the loom, the casingrods 31 replaced. the terminal lowered to normal position, the loom thenbeing ready for operation. If desired to run with a lease, only one ofthe sets of rods 14 or 16 is removed.

While the above description applies to the pile warps, the invention isequally adapted to the back warps, as shown in Figs. 2. 3 and 4. In suchadaptation of my invention the drops 5 are supported upon a section ofthe war between the rods 17 supported in brac ets 18 adjustably securedto the U- shaped end pieces 19 by bolts 20. Each of the end pieces 19has an n ward extension 21 against which the terminal supports 22 and9.3 are adapted to be clamped. As shown in the drawings, the terminalsbear against the sides of the supports and the latter are normallyseated upon the end pieces 19. The extension 21 comprises two legs, asshown in Figs. 3 and 4, and, through the space 24 between the legs,bolts 25 are passed, the said bolts also assing through slots 26 in theterminals, an having nuts 27 which, when tightened up, clamp theterminals in position against the sides of their supports and againstthe extension 21, and also through the two outer terminals clamp thesupports 22 and 23 a ainst the extension 21. As shown in Fig. T, one ofthe clamp supports, as 22, is provided with a laterallyextending head.29, and the other clamp supportis provided with a correspondinglyshaped socket to receive the head 29. This interlocking means preventsthe clamp supports .22 and 23 from spreading when the nut 27 isloosened.

When it is desired to take a lease on the back warps. the nuts 27 areloosened and the supports 22 and .23 with the teminals, raised, and theterminals are then clamped in their raised position as shown in Fig. 4.In the loom shown there is always a lease rod at .28 and when the newlease is to be taken said rod is moved close to the terminal supportingframe thus spreading the warps through the frame. A lease rod is thenplaced between the spread wraps at the left of the frame and rod 28removed. Then a. rod 32 is placed at the right of the crossing of thewarps on the right hand side of the frame and moved close to the framethus spreading the second part of the lease through the frame. A secondrod 33 is then placed between the spread warps at the left of the frame.The new warps are then tied in and the lease run back and rod 28 placedas in normal running.

In a plain loom where there is no lease rod between the harness and theterminal, a lease is taken by raising alternate harnesses, drawn backand passed through the terminal frame as above described.

The above-described feature of an adjustable terminal is of particularadvantage in a double pile fabric loom, such as illustrated,

and also where the warp is inclined to roll or to become mattedtogether, or when crossed, as it sometimes is, by improper handling whenit is better to run without the lease rods. \Vhen the loom is runwithout lease rods, then it is necessary to make a new lease at the endof the warp and to do so it is necessary to make the terminal adjustableto give the necessary space through which the lease rods may be )assed.

\Vhen the terminals are raised the dctcctors or drops remain in theirnormal position as they are held in such position by the warp threads.The terminals are merely moved to the top of the opening in the dropdevices and then clamped in the raised position.

\Vhat I claim and desire to secure by Letters Patent of the UnitedStates is 1. A loom having a stop motion comprising drop devices carriedby the warps, a circuit terminal with which the drop devices co-act, aframe in which said terminal is supported, lease rods so located withrelation to the supporting frame as to pass a least through the support,and means for adjusting said terminal in its support when tlu lease istaken.

2. A loom having a stop motion eompris ing drop devices carried by thewarps, a eir cult terminal with which said drop devices co act, a framein which said terminal is sup ported, lease rods so located withrelatioi to the supporting frame as to pass a leas through the supportbelow said tcrminaf and means for raising said terminal in it supportwhen the lease is taken.

3. A loom having a stop motion compris ing drop devices carried by thewarps, circuit terminal extending transversely r the loom and with whichsaid drop devim co-act. a frame in which said terminal supported, saidframe having guide bai over which the warps are passed, lease rm solocated with relation to the supportin frame as to pass a lease throughthe supper and means for moving said terminal awe from said guide barsto provide a spa through which a lease may be passed.

In testimony whereof I have hereun signed my name in the presence of twosu scribing witnesses.
